Detailed Description

Pulls bytes from ra8_psa_crypto_random() once a second and dumps them as hex over the console, toggling LED1 on each emit so the heartbeat is visible without a serial terminal.

This is not entropy. The RSIP-E50D TRNG has no working register interface on this silicon – ra8_rsip_trng_read fails closed – so ra8_psa_crypto_random here returns a deterministic software stub that produces the same stream every boot. The verdict line says so in as many words. A green result proves only that the API path runs and the stub is not stuck; it says nothing about the quality of the output. Real random bytes need an FSP-derived RSIP TRNG procedure.

No external transceiver, board or harness required.
